Reading the passage
We've already predicted apparent benefits from wine that may come from grape compounds. The grape-juice result helps connect those two ideas: a similar effect appears without wine's alcohol.
What we’re looking for
For the main point, keep both the possible benefits and their proposed source. The author offers a developing explanation, not conclusive proof.
Working the answers
- A
The opening criticizes research that overlooked wine's distinctive effects. A extends the point to alcoholic beverages generally and stops before the research and grape-compound explanation.
- B
We're told there are several contributing factors, but not that scientists believed lipids were the sole cause of heart disease. Correcting that supposed belief isn't the argument's focus.
- C
Slower absorption is one finding, not the central explanation. The stated comparison is also with distilled spirits, rather than every other alcoholic beverage.
- D
The evidence isn't presented as definitive, but this makes the limitation the whole point. The author is developing a positive explanation of apparent benefits, not merely announcing that they remain unproved.
- ECorrect
This matches our prediction: apparent beneficial effects that may be tied to particular substances naturally present in grapes (paragraph 3). The final grape-juice study supports that proposed source. Appears and may preserve the author's caution.
